PASTRY-MAKING MAQHNE.

Application filed J'iine 2, 1916.

" invention has lor its object to provide certain new and uselulimprovements on the lmachines disclosed by my prior patents.

among' which may be mentioned latent No. LOTLUQT, issued Aiugiilst 2li,1913; and latent No. 1,075,625. issued October ll, 191B.

ln the iirst ot' the above mentioned patents, no special provision ismade for the escape of the steam and vapors at the conlmencement ol' thebaking operation.

ln the second ot the above mentioned patents7 l have provided a curvedtrackwav, referred to in the said patent by the reference iuuneral 260,the object o'l which is to allow the core bars to be raised by thepressure within the molds at intervals during the commencement ot' thebakingA act. to alternately allow the escape of the steam and resent the-cores in the molds, so that a semiplastic batter may retain itsl moldedform during the operation of releasing the steam.

bly present invention is a modification of the means shown in Patent No.'1,075,625 for allowiirer the escape of the steam referred to and. inthe present inventiop7 itihis is ac-` complished by providing` a seriesoi.' yieldable rollers which are designed to engage and press down thecore bars at the stop positions immediately following the loadingposition and to release the corey bars during their travel from one suchstop position to the next succeedingl position, the linal pressureroller coming into action-after the es capo ot the steam to tinallvy sait the core bar in the mold where it reinaius during the time of thebzikine` operation.

'lhe invention also resides in those novel details of construction,combination and arrangement ol parts. all ol which will be fullydescribed and then be specilically pointed out in the appended claimsrelierence beine' had to the accompanying draws ings. in which:

Figure l is a plan view of a portion ot' a machine such as disclosed inmy patents above Spcification of Letters Patent.

referred to and showing the location of the improvements whichconstitute the present invention.

Fig. Q is an enlarged elevation and part section et the improvementsconstituting the invention7 portions ol the molds and eore bars being,Vindicated in liull lines in the stop" positions and in dotted lines inthe intermediate positions through which the molds are moved. 'i Fig. 3is a horizontal section on substantiallvthe line 8-23 o'li Fig. l

F i1): l is a detail perspective view and part section showing one ofthecore bar pressure members.

In the dra wings in which like numerals of reference designate likeparts in all the figures, l is the standard base on thel center 'l ofwhich the rotatable wheel is ino'unted. The wheel 3 has a rim on whiehare studs tv to which the arms 51T ot the molds 5 are pivoted to openscissor `fashion. The molds 5 have mold cavities shaped to forni thedesired article (in this wise, ice ereain cones) and the molds areprovided with the usual opening;A and closing and locking devicesillustrated in in v patents above reieri'ed to (not shown in the presentdra wings).

The. cores lo are .mounted on the usual core har il which is connectedto the wheel frame by the usual link ta, so that the cores may be liftedout of the moldsand dipped into the usual. batter tank (not shown) bythe usual corey lilting and loading mechanism.

lt and lo* designate the usual eore unlocking* and relocking` guidesthat cooperate with the eore lati-hing devices 13 (see Patent No.1,071,027 above referred to).

ln Fig. 'l ot' the drawings, the position marked D is the loadingposition oi the wheel and the positions F and (il respectively are thethree succeeding` stop posi* tions during which the baking operation isinitiated 'and itis during this time that the formation ol steam is atits height.

ln order that the eore bars ma),7 be allowed to rise by the steampressure. they are not looked until position (l is reached but the corebars are alternatel)7 pressed down at positions ll and l" and releasedbetween positions Ff-lC and FMG, to permit the ess cape of steam. 'lhisis accomplished b v providing a bar (l which is supported by stand ardsand braces tit) Yfrom the traine The ba-r Gl is provided with pivot pinG2 on which are fulcrumed levers 63 that have shoulders 73 to engagestop pins 69 when the pressure rollers 72 are not in engagement with thecore bars ll.

The levers (S3 are pressed downwardly by the tie springs 6G, one arm ofwhich is bent at G5. to enter aY recess (il in the respective lever 63while the other arm G7 of the spring lies under a stop pin (S8 on thebar 6l. The levers 63 are bored and tapped at 70 to receive the bearingscrew 71 on which the respective pressureroller 72 is journaled.

16 designate the usual oven covers carried by the core bars l-l.

In operation, afterthe mold has been loaded at position D, the wheel isturned one Step until the mold arrives at position E at which time thecore bar will receive pressure from the spring GG through the pressurerollers 72 at position E, thus forcing the core bar downwardly andinserting the cores to their fullest extent into the cavities. As thewheel is turned another step to bring the particular mold to position F,it will have to pass from beneath the roller 72 at position E and atthis time the steam pressure will raise the-core bar as indicated indotted lines in Fig. 2, thus permitting the escape of the steam; Asposition F is reached, the core barwill be again forced down into itsclosed position and again released after it passes position F on its wayto position G, so that any further fomation of steam may berelieved'between positions F and G before the filial closing pressure is-applied by the roller 72 at position G and the core locking deviceshave been reset.

From the foregoing description taken in connection with the accompanyingdrawings, it is thought that the Complete structure, operation andadvantages of the invention will be clear to those skilled in the art. lv

What I claim is: 1. In a machine of the character stated,the combinationwith the rotatable carrier, the molds and the core bars carried thereby;of a core bar presser for pressing said bars on the molds, said pressercomprising a supporting bar, a lever pivoted to said snpporting bar, apresser roller carried by said leverfa spring for forcing` said leverdown and a stop for limiting the downward moyev ment of said lever,substantially as shown and described.

2. The combination with the intermittently movablemolds and core barstherefor; of a bar located above the molds in the direction of travel,a-series ot' yieldably supported core bar pressers mounted on said barand adapted to engage said core bars as the same' are moved beneath -thepressers, to forcethe cores into the molds, said core bars being free tolift when between adjacent pressers of the series, said yieldablysupported core bar pressers con'iprising levers pivoted lo said bar,springs for forcingl said levers to the pressing` position. stops forlimiting' the movements of said levers,

and 'presser rollers carried bv said levers.
